Is Ethylene/Propylene Copolymer a Good Ingredient?
Good: a dependable film former and structurant that improves wear and texture in oily or anhydrous formats, with a low likelihood of irritation due to its inert, high-molecular-weight nature. Its contribution is textural rather than a direct skin benefit, which keeps it at Good rather than Great.
